rnm'zrr iadmacnmn To all whom it may concern:

Be it known that IQAnos H. SMITH, a citizen of the United States,residing at the borough of'Bronx, in the city of New York,

. 5 'county'of Bronx, and State of New York.

have. invented certain new and useful Imjprovements inPrlntingsMachines, of which i .the following is a specification,referencebeg' ing had therein to the accompanying draw-f;

My invent-ion relatesto printing machines.

I furthermore provide a controlling. meansforthis registering mechanism which will create. slack upon one side ofthe printing couple and take up this slack on the other f side thereofto permit the adjustment of the machine, even while it, is running. tocompensate'for any slight loss of register due to stretching of,orshrinkage in. the paper.

. The invention consists primarily in a printmg maclnne embodyingtherein a printing couple ncluding therein an intermittently operativeimpression cylinder and an inter- Inittently operative paper feedmechanism adapted to feed a continuous paper web in relation to. saidprinting couple whereby the feeding movement of said web will continueduring the impression interval and said paper will remain stationaryduring the. nonprintlng interval; and 111 such other novel features ofconstruction and combination of embodying my invention with thereofbroken away;

In the embodiment of my invention shown in the drawings I haveillustrated it in conmachineare indicated'at 1 and 2, the form nectionwith a machine embodying therein both a rotary impression cylinder and arotary form cylinder, but the invention may be applied tomachines usingother types of form cylinders without substantial modification. 7 y

In the drawings the side frames of the cylinder at 3 and the impressioncylinder I i or D-roll at While" the machine shown isan engrav1ng,.intaglioor undersurface printing press, the illustration of the printingcouple is merely conventional and the inking, wiping and polishingmechanisms are omltted as such are old and Well-known and are notmaterial to an understanding desired source to the shaft 5 of the gear6.

Fig. 5 is a similar view showing the posi- .t1on of paper with each ofmy present invention. At. 5 I have shown the main power shaft of themachine carrying the gear 6 in mesh with a gear 7 through which power istransmitted to the form cylinder; Power may be derived from any as theelectric motor 8 belted Inthe form of the invention shown, theimpression cylinder or D-roll 4: is continuously rotated by means of themeshed gears 9 thereon and upon the form cylinder tion thereto, saidmechanism being operative to feed the paper only during the printinginterval and becoming moperative immediately upon the disengagement ofthe impression cylinder or D-roll4 with the 'printing surface carried bythe form cylinder. The peripheral velocity of this mechanism is socontrolled as to be inaccord with'that of the printing couple.

Inthe form or the invention shown, this mechanism comprises'a pair offrictlon rolle1's 10 and 11, one of which as IO is'driven from theimpression cylinder'or D-roll by the chain and sprocket mechanism 12.These rollers are so constructed and arranged that the feeding intervalthereof will accord with the impression interval of .the printingcouple.

To adapt a machine to work with plates of different dimensions,Fpreferably provide the rollers 10 and 11 with continuous frictionsurfaces and use acontrolling meanswhereby said surfaces Wlll be pressedtogether when it is desired to feed the web, andwill be automaticallyseparated when it is desired to prevent a further feeding movementthereof. To insure accuracy in the operation of the feedin mechanism,and

prevent the formation of s ack between the feed mechanism and theprinting couple,

and also the feed of the web by the rewinding mechanism when such isused,.I provide a clamping mechanism whichis operative upon the webwhen'the feed rollers 10 and 11 are separated and is inoperativethereonwhen said feed rollers are operative.

Th1s clamping mechanism comprises oppositelv disposed'members 13 and 14:having friction surfaces between which the paper ,web' is adapted topass after leaving the feeding rollers and controlling means for saidclamping members, so constructed that dESI AVAlLABLE CO3 The feedrollers and 11 are adapted :o be positively driven by the intermeshing'gears and 21 carried thereby respectively, 1nd the roller 11 is normallythrusttoward :he roller 10 by means of the springs 22 actmg uponbearings 23 slidably mounted in the side frames ofthe machine,

To accomplish the intermittent separa- JlOIl of the rollers 10 and 11, Iprovide the )pposite ends of one of them as 11 withbear ng disks 24adapted to 006 erate with cams arried by the other ,rol er as 10; Theeight of the riser upon each' of said cams is preferably such as toeparate the friction surfaces of the rollers withoutdisengaging he gears20 and 21,thus avoiding any possioility of a loss of mesh ofthese gearsand a Y, resultant loss, in the synchronism ofsaid gears and the D-rollor momentary delay in the initiation of the feeding movement of" saidrollers.

The length of the riser will determine the inoperative interval of thefeeding rollers,

and to adapt the machine to a variable feeding movement of the paper inconformity with the requirements of plates of different sizes, I soconstruct said cams that the length of said risers may be varied asdesired. To secure this result, I form said cam of two similar sections25 and 26, one of which as 26 has segmental slots 27 therein throughwhich project the clamping bolts 28 adapted to secure said cams in anyadjusted position.

The clamping member 13 preferably consists of a rotatable cylinderhaving a friction surface, while preferably the member 14: isnon-rotatable and is provided with angular arbors vertically movable inways in the side frames 1 and 2. The member l l is acted gupon by thesprings'29l1aving a, normal.

thrust toward the member 13, The ends of the arbors of the member lthaverotatably mounted thereon, however, circular disks 3O mounted thereonthe gears 31 which are driven from the gears 20 .by means of theintermediate pinions 32; The gears 20'and 31 are of the same dlameter toinsure accuracy in the timing of the operations of the feeding mechanismand the clamping mechanism.

The feeding cam cooperating with the disk is composed of two sections33- and 34 the first of which is secured to and movable with the gear 31and the latter of which is provided with segmental slots 35, throughwhich the clamping bolts 36 project in a manner to permit the setting ofthe disk 34 in'any adjusted position relatively to the section 33. Thecam disks 33' and 34 while similar in construction to the disks 25 and26 differ therefrom in the length of the riser, the length of the riserupon the composite cam 3334'when adjusted to its full length being equalto the length of the fall uponv thecam 25-26 when the riser isadjus'ted, for its shortest length. This construction results from thenecessity for having' the cam 3H4: operative during substantially theentire interval when the cam 25 -26 is inoperative and havingthe clamp:

.ing mechanism inoperative during the entire interval when the feedingmechanism is'operative. The cams upon the gear 20 and upon the gearwheel31 are set at 180 apart and the length of the risers upon thesecams respectively is such thatif taken together they would occupy a.full 360.

It is to be observed that while the feed rollers 10 and '11 arepositively driven, the

roller 13 is an idler roller and the member 14 is preferablynon-rotatable' in order to avoidany possible feed of the paper by therewinding mechanism.' The disk 30 is made rotatable merely to minimizewear thereon.-

At 37 I have shown. a roll of a continuous paper-Web mounted in suitablebearings 38. Guide rollers 39, 40v and 41 are arranged betweensaid'bearin gs 38 and the printing couple, a guide roller 42 is arrangedbetween the printing couple and the rollers 10 and 11, and a guideroller 43, is

arranged between the clamping mechanism and the rewinding reel.

To adaptthe'machme to printingin registering colors, 'I provide aregistering mechanism adaptedto vary the position of the web withrelation to the printing couple, this mechanism being so constructed asto be capable of either advancin the web or Withdrawing it. To securethe desired result, I provide means which will impart movement only tothat portion'of'the' web adjacent the printing couple thus pern'iittingadjustment for register without disturbing the feeding mechanism orcreating permanent slack in the Web.

. In the form of the invention shown, I provide means operative uponopposite sides of the printing couple whereby slack in the web maybecreated upon one side thereof and be simultaneously taken up upon theother side thereof. Thls mechanism com- SESTAVAILABLE CCDl prises asupport or supports 44 for the guide roller 42, 'slidably mounted in theside frames of the'machine and acted upon by feed screws 45 to impartthe desired reciprocatory movementthereto. Mounted between the guiderollers 40 and 41 is a'vertically reciprocatory roller 46 mounteddn asupport or supports 47 acted upon by the feed screws 48. The feed screwsand48 are of substantially thesame pitch, so as to secure equality inthe movement of the rollers42 and 46. Carried by each of the screws 45is a beveled gear 49 in mesh with a gear 50 carried by the shaft5l. Thescrew 48 is carried by, and rotatable with a shaft 52 which isoperatively connected with the shaft 51 by means of the shaft 53 and thebeveled gears 54 and 55 carried thereby, and the beveled gears 56 and 57carried by the shafts 51 and 5'2-re spectively. The various gears are soset that as the guide roller 42 is moved toward the? printing couple theroller 46, will be simultaneously moved downwardlv' with the same Iguantity of movement; and aslthe roller 42 is moved away from saidprintingjcouple said roller 46 will be raised. ,.,Either or both of theshafts" 51 and 52'areprovidedy'with hand wheels 59-60 by 'which'theytmaybe actuated. f 1 The power transmission mechanism extending from thescrews 45: to-the screw'48 upon one side of the machine is connected theother gear 49;1 1pon' the other side of the I A -to a similar mechanismon 't-hefiopp'osite side of the machine so as to cause simultaneousuniform movement 0f -both.'- ends of the rollers in any desired manner.-In the drawing's, ,I have shown a chain'and sprocket mechanism 58extending fromone car 49 to machine. v t The operation of the'hereindescribed-nia-- chine 'is substantially as. follows:

'11 when the orm cylinder is not'in engage- -ment with a plate, andsince the riser of the fI-nstarting'arun of the press, the end ofjtheweb is drawn from the paper 'roll 37 and passed over the guide rollers39, 40 and 41' and under the roller 46, thereafter being passed betweenthe form cylinder 3 and im-' pression cylinder or D-roll 4 and aboutthe.

guide roller 42. From the roller 42, the web is passed between the feedrollers 10 and 11 and the clam ingmembers 13 and 14, the .latter of whicmay be separated manually to permit the passage of the paper. Theend ofthe It'willbe observedthat'in order -toz-pere' mit' the" passage ofthe'ipaper between the form cylinder and the impressioncylinder-rapex isthensecured to the-re- .windingree 15:" 1

'or' D-roll the latter must not be in engagement with a -plate u on theframe.

Since the riser o the cam 25-26 is so set as to be 0 erative to raisethe feed roller cam 33-34 is set in a relation diametrically vwill'pass'the disk 24 peri'nitting'the springs -22 to force the roller11 downwardly to an thereof.

opposite to that of the riser upon the cali' 25-26, said feed rollers 10and :11 will 'b of the cam 25-26 will be engaged with th disk. 24, andthe disk 30 will be engaged with the fall pf the cam 33-34. Hence therewil be no feeding movement of the paperas thi; cam members 13 and 14will prevent tht friction drive 156 of the rewinding' reel 15; exertingapull upon the paper beyond saio clamping members.

With the continued operation of the ma chine, however, the riser of thecam 25-26 extent to develop the requisite friction upon the paper toinsure the feeding movement Simultaneously with this movement of theroller-11, the elongated riser upon the cam 33-34 will engage the disk30 and raise the clamping member 14, thus permittin the re-Z windingmechanisms to take up t e slack; resulting from the feeding movement ofthe iollers 10 and '11. The initiation of th feeding movement bytherollers 10 and 1;!

and the releaseof the clamping mechanism will occur substantiallysimultaneously with the initial engagement of the impression cyl-i inderor D-roll with the plate, or other print-f ing surface, upon the formcarrier 3; and by reason of the fact that the peripheral ve'locity ofthe feed roller conforms to that of the form cylinder and the D-rol'l,"the paperwill be fed at the proper speed.

t that interval when the impression cylinder or D-roll passes from itsengagement with the .plate upon the form carrier, the riser upon the cam25-26 will become operative upon the disk 24 to raise the feed roller 11and make said rollers inoperative to cause: a further. feedingmovementof the web. Si-f multaneously withxthe lifting of the roller ll-againstthe tension of, the springs 22',- the riserupon the cam 33-34 willbecome inoperative." as to the disk 30 permittingthew c amping member 14to descend under the control of its springs 29, thus'instantly arrestingthe feeding movement of the paper by the rewinding mechanism.

It will thus be observedthat I secure with a continuously oeratingrinting couple, an

intermittent fee .of a we in relation there- "ing rollers sponding withthe inoperative interval of to, thus permitting that dwell betweenimpressions which is essential in some classes of printing, as fromengraving, intaglio or undersurface plates, and permitting theimpressions to be brought closely together upon a web with a resultantmaterial saving of paper.

WVith a continued run of the press, the feeding rollers 10 and 11 willbe actuated to make them operative and inoperative alternately, theoperative interval corresponding with that interval when the impressioncylinder or D-roll 4 is in operative engagement with a plate upon theform carrier 3; and the clamping mechanism will be actuated to make itinoperative and operative alternately, the inoperative. intervalcoinciding with the operative interval of the feedand the operativeinterval correthe .said rollers.

Under the, conditions above described, it will be observed that thelength of the risers upon the cams -26, and 33-34 determines theduration of the. feeding interval of the 'web, which: must correspondwith the size of the plate from which the impression is being made as tothe length of said plate. Hence, if plates of different sizes are usedupon the machine, to effect the maximum saving of paper, cams havingrisers of different lengths must be used, the length of said risersbeing determined by the size, or length, of the plate.

By using sectional cams as above described, having similar cam risersupon each section, I am enabled to adjust the length of said risers uponsaid'cams-so asto avoid the necessity for the substitution of cams whensetting the machine for a run with plates of any particularsize. Forinstance,

' if it is desired to run the machine with a plate smaller than that forwhich the machine is set at any time,{ the= clamping bolts 28 and 36 arereleasedandythe section 26 is turned in either direction according tothe position of the. plate upon the form carrier, and the said sectionis reset by means of the said bolt in its adjusted positioh. Thiselongation of the risers upon said cam '25-26 will have the effect ofprolonging the inoperative interval of the feeding rollers. Then the camsection 34; is turned in the same direction as that of the cam section26 and to the same extent. thus shortening the riser upon the cam 33--34, without changing the position of the init al rise of the cam in away to vary the relative initial operation of either cam. By varying thelength of the risers the quantity of the feeding movement of the papermay be regulated.

It will be observed that as to time, the efiect of the feeding rollersand of the cam cchanism. are always reversed and that this reversalextends through'all of the adjustments of the said cam, hence when theriser of the cam 2526 is set for its shortest length, the riser of thecam 3334 will be set for its greatest length, and vice versa.

When the clamping mechanism is inoperative, the member 13 acts merely asa guide roller for the Web, but inasmuch as the gear 31 is looselymountedupon the arbor of said roller,.the rotation of said roller isentirely independent of that of said gear which is thus permitted toturn continuously with the feed roller 10. While the feeding roller 10rotates continuously,

it will have no operative efiect in feeding the paper except when theroller 11 is in the operative relation thereto.

In order to adapt the machine for use in color work, I preferablyprovide the regis-. tering mechanism which I have described. In runninga web through the machine, which web has already received oneimpression, it is necessary to have a succeeding imprint in registertherewith. If it is found that as a result of loss of register, it isnecessary to advance the web slightly, either of the hand wheels 59-60are turned so as to rotate the screws 4'548 in a manner to raise theroller 46 and simultaneously thrust the roller 42 away from theimpression cylinder or D-roll. The result of this operation will be thecreation of slack between the D-roll and the roller 46, which slack willbe taken up by the advance of the roller 42. If it be desired towithdraw the paper slightly either hand wheel 5960 is turned in theoppositedirection with the resultant creation of slack between theroller 42 and the D-roll, which slack will be simultaneously taken up bythe roller 46 which will be forced downwardly simultaneously .with theretraction of the roller 42. By connecting the mechanisms controllingthe rollers 42 and the roller 46 by means whereby said rollersfaresimultaneously operated, and to the same extent, I am enabled to effecta movement of only that portion of the web adjacent 'to 'the' D-roll andform cylinder. Byi-limit ing' thelength of the section of web ted uponby the registering mechanism,TI ahgenahled to secure extreme nicety inthempvement oftM paper; and a movementfiw'hich not --require anyvariances inthe':adjustment/of any other part of the machine. Hence,thisregistering mechanism may be advantageously used in con unction with apaper feed mechanism, and permits the construction of a machineembodying such a feed mechanism, wherein adjustment for securingregister may be had without disturbing the relation of the feedingmechanism to the web, or requiring any change in the adjustments of saidfeed mechanism.

It is not my intention to limit the invena printing couple including anintermittently operative impression cylinder, an intermittentlyoperative paper feed mechanism adapted to feed a continuous paper web inrelation to said printing couple whereby the feeding movement of saidweb will continue during the impression'interval and said web willremain stationary during the non-printing interval, a pair of frictionmembers between which the web passes after-leaving said paper'feedmechanism,-
